Title: Improvements in Machines for Removing Superfluous Solder from the Exterior of Tin Cans.
Inventor: IBBERSON RICHARD WEBSTER
Filed: 1903-01-06
Granted: 1903-03-26
Abstract: 300. Ibberson, R. W., [Fellows, O. S.]. Jan. 6. Soldering.-A. machine for removing superfluous solder from the exterior of tin cans is provided with a convex guiding-surface for the cams in conjunction with an opposed flexible can-forwarding surface, the arrangements being such that the cans may be fed from either end of the machine. By contracting the space between the stationary and the moving guiding surfaces, effective contact with the cans is preserved although the cans may vary slightly in diameter. The machine with its covers removed is shown in plan in Fig. 9. The stationary guiding-surface E with spring jaws e<3> diverges from the centre in both directions. The moving band D is stretched by the device F which consists of an idler pulley in a yielding bearing, the bearing being subjected to a pull by a weight or equivalent mechanical expedient. At each side of the solder-brushing apparatus are situated the fluid-blast jets O, O<1>, so that the end plate of a can is first subjected to a blast and is then brushed and again treated to a blast. To provide the second blast, a pair of nozzles are provided, one nozzle being directed against the inner side of the end plate of the can while the other is directed against the angle of the flange. The cans are rotated by wheels H, H which are adjustable. The brushes are also mounted in adjustable bearings and are actuated by spiral gearing as is described in Specification No. 212, A.D. 1903. The convex guiding- surface is made adjustable relatively to the forwarding-surface D by suitable devices, the surface D being also adjustable. The retarding-wheels H, H are rotated by belts from the shafts I, the slack of the belts being taken up by a tension regulator. An overhead guiding-rail for the cans is arranged to suit cans of different heights.

Title: Improvements in or relating to Power-storing Brakes for Railway-trains, Tram-cars, and Road Vehicles, including Bicycles and the like.
Inventor: QUICK GEORGE
Filed: 1903-07-03
Granted: 1903-12-31
Abstract: 14,799. Quick, G. July 3. Starting and stopping.-Relates to apparatus for storing up the energy of a moving vehicle in stopping, and for utilizing the energy in re-starting it. In the case of road vehicles or other vehicles with fixed axles, the apparatus shown in Fig. 7 is employed. The hub of each of the hind wheels is formed with a sleeve which extends along the axle A<111> and has fixed to it two ratchet-wheels L<11>, L<111>, Fig. 10, with oppositely-directed teeth. To apply the brake, a chain-wheel F<1> is made to engage the ratchet-wheel L<11>, and the motion of the vehicle then causes the wheel F<1> to drive a chain-wheel C, Fig. 7, by means of a chain D. The chain-wheel C is geared by toothed wheels to a drum R which winds up a chain V connected to a spring d. To re-start, the wheel F<1> is released, and the spring d, acting through the drum R, a chain-wheel G<111>, a chain D<1>, a chain-wheel G", and an arrangement of pawls, drives the ratchet-wheel L<111>, Fig. 10, and propels the vehicle. The arrangement of pawls for connecting the wheel G<11> to the ratchet-wheel L<111> is similar to that described in Specification No. 18,558, A.D. 1902, [Abridgment Class Mechanism &c.]. When disconnected from the ratchet-wheel L<111>, the wheel G<11> is supported freely by a ring of small wheels carried by the hub. The wheel F<1> is similarly supported by a ring of small wheels running on a grooved collar on the axle-tree N, and is connected to the ratchet-wheel L<11> when required by a series of pawls P, Fig. 9. Each of these pawls is pivoted near the middle and carries a roller at each end ; a spring tends to press one end into engagement with the ratchet-wheel and the other end outwards through an opening in the wheel F<1>. The pawls are normally kept away from the ratchet-wheel by two semicircular guiding-pieces X pressing against their outer ends. These guiding-pieces are formed on the ends of pivoted arms which are pressed apart by a spring S, Fig. 7, and can be brought together by a slide S' and a hand-lever k<11>. The starting-gear may be prevented from working by a pawl u, if required, as for example when going downhill. In the case of vehicles with elastic tyres which would be injured by locking the wheels, auxiliary wheels are fitted for operating the braking-apparatus, and are mounted in a frame which can be raised or lowered to engage the wheels with the road.

Patent GB-190404994-A (GB)
Title: Improved Manufacture of Coloured Photographic Images or Prints and of Sensitive Surfaces therefor.
Inventor: IMRAY OLIVER
Filed: 1904-02-29
Granted: 1904-12-31
Abstract: 4994. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Feb. 29. Producing coloured photographs; sensitized plates and films; printing.-Coloured photographic prints are produced by using as the sensitized material leuco-bodies of orgamc dye-stuffs mixed with a substance containing one or more nitrogen-oxygen groups which can be eliminated. Examples of this latter kind of substance are the nitric acid esters of the carbohydrates, such as nitro-cellulose. If, for example, a solution of leuco-malachite-green in alcohol or ether be mixed with some collodion, and the whole be poured on baryta-paper, this paper, when exposed under a negative, gives a clear green positive. The image is fixed by dissolving off the unconsumed leuco-body by the aid of solvents such as chloroform, the hydrocarbons of the benzene series &c. The sensitiveness of the preparation is increased by the addition of traces of certain oxygen carriers such as platinic chloride, quinoline; &c. By this process, photographic images of any colour may be obtained, and the process is thus especially suitable for tri-colour photography.

Title: Improvements in or relating to Machines for Milling Fret saws and the like
Inventor: FRIEDRICH HEINRICH
Filed: 1904-03-29
Granted: 1904-09-01
Abstract: 7512. Friedrich, H. March 29. Milling.-A machine for milling the teeth of fret saws and the like has a cutter spindle 9, Fig. 3, mounted in a forked slide 11, vertically adjustable on a horizontal slide 13, Fig. 1, which is reciprocated by a cam on the driving-shaft 3. The spindle is driven by bevel-gearing and universal joints. The saw is mounted in a holder 32, and is raised into contact with the cutter 10 during the cutting by a guide 22 operated by a lever 20 from a cam on the driving-shaft. The slide 13 is reciprocated during the cutting of each tooth by a multiple-throw cam 14. After a tooth has been cut, the guide is lowered and the saw falls clear of the cutter, so that the saw and holder may be moved laterally one tooth by a worm 37, operated by a cam 24, link 27, and ratchet-wheel 29, and gearing with a worm-wheel 36. The spindle of the worm-wheel carries a hand-wheel 35, and can be locked in its bearings on the slide carrying the holder 32, so that the saw is spaced by the worm and ratchet-gearing, or the spindle may be released and the worm-wheel rotated to traverse the slide by hand. The depth of the teeth is varied by adjusting the fulcrum 50 of the lever 20, which may have an eccentric formation so that it may be turned for fine adjustments, or it may be moved in a slot 53 for coarser adjustments.

Title: Apparatus for Delivering Single Sheets of Paper or other similar Thin Material from a Pile of Sheets.
Inventor: ROBINSON THEODORE DUSENBURY
Filed: 1904-05-31
Granted: 1904-10-27
Abstract: 12,311. Robinson, T. D. May 31. Feeding sheets.-Relates to apparatus for delivering single sheets of paper or similar thin material, such as letterheads, envelopes, &c. to customers, so as to prevent waste of paper. A hand-lever 12<1>, being depressed, causes a suction device to pick up the top one of a number of sheets &c. The picked-up sheet is knocked off the suction device by a fixed finger and is impelled by a spring down a shoot to the exit 23. The sheets are slightly fanned out and placed, through the opening 1 of the casing, on to a table 3, which carries sleeves 5 sliding on guides 5<1>. The table is moved up periodically, as the thickness of the pile of sheets diminishes, by a worm-wheel 6. The wheel 6 is mounted on a screw shaft 8 and driven by a worm 7 connected by intermediate shafts and gear to a handle b. The air-pump barrel 10 is carried by a frame 9<4>, sliding on guides 9 and drawn up by a link 15 and rocking lever 16. The lower part of the air pump is covered by a sheet of india-rubber having a central hole, and rests on, so as to overlap partially, the pile of sheets. The pump plunger 11<1> is connected by a link 1 to the hand-lever 12<1> which is pivotally connected by an arm 13 to the lever 16. The levers 16, 12<1> and links 15, 11 are each formed of a pair of thin plates. The link 13 and piece 14 are single bars. The piece 14 forms a guide for the lever 16. On pressing down the lever 12<1>, it and the arm 13 rock on the pivot connecting them and draw up the plunger 11<1>, thereby causing the top sheet of the pile 2 to adhere to the rubber valve. As soon as the lever 12<1> sinks on to the lever 16, the combination of levers rocks on the pivot 21 so that the air pump is then itself lifted up and strips off the top sheet from the underlying sheets. The lifted sheet is released by contact with a stationary striking-finger 9". The springs 9<3>, which are forced aside by the frame 9<4>, then send the liberated sheet down the shoot 22. The hand-lever is returned to its original position by a lever 18 controlled by a spring 20, the dash-pot 17 which works with lever 16 preventing any jar.

Title: Improvements in and in connection with Casks or Vessels from which Liquid is Discharged Under Pressure.
Inventor: IMRAY OLIVER
Filed: 1904-06-30
Granted: 1904-08-18
Abstract: 14,752. Imray, O., [Deutsche Steinzugwaarenfabrik f³r Canalization und Chemische Industrie]. June 30. Direct air-pressure apparatus. - Liquids are discharged, under pressure, from casks or other vessels by an arrangement such as that shown in Fig. 1. In the vessel are two floats e,f, resting one on the other, as shown. The lower float f has a flange or projection at the top which, when the liquid is withdrawn below a certain level, rests on, and closes, the valve of the compressed-air inlet d. The upper float e is connected with the valve c by which the air outlet is closed and opened. Liquid being admitted into the vessel, the floats rise until the valve c closes the air outlet. The valve of the inlet d is then released, and compressed air enters to force the liquid from the vessel and up a pipe g, lifting the valve b. The float f soon falls, closing the inlet d, while the float e still remains in the raised position to keep tha valve c closed. The compressed air is thus economized. It first acts at full pressure to cause the discharge of the liquid at a rapid rate, and then by expansion to discharge the remainder. When the pressure in the vessel falls below a certain limit, the float e falls, thus opening the air outlet, and permitting the liquid from the supply reservoir to now again automatically into the vessel. The rate of discharge from the vessel may be regulated by a throttling action. Thus, under high pressure, the valve b is adapted to rise and more or less choke the entrance to the tube g, or the liquid may be caused to move in a circle along a passage i, or the air-supply valve may be regulated. In case of fluctuations in the airpressure supply, the bottom of the float f may be made concave so that the air entrapped therein is compressed to a high pressure, when the float sinks more readily, and vice versÔ a decrease in pressure renders the float more buoyant. The float regulating the discharge may be placed at the bottom, instead of at the top of the vessel, when the liquid level is to sink to the botton of the vessel. When the last charge will not fill the vessel, the reversal must be made by hand, for example, with a three-way cock.
